it had been debated whether genes were made of proteins or DNA. Many believed they were made of proteins because proteins had a very complex structure, and DNA only had 4. But after the Hershey & Crick experiment, it was cocluded that genes were made of DNA
What was the Hershey & Crick experiment
used radioactive material to determine if genes were composed of proteins or DNA. They predicted that if genes were composed of DNA than the radioactive material would be found on the outside of the infected cell ghost capsids and the radioactive DNA would be found inside of the cell
What was the conclusion of the experiment?
genes were made out of DNA, the radioactive proteins were found in the ghost capsids and the radioactive DNA was found inside of the cell
what is the primary structure of DNA molecules?
Backbone made up of sugar and phosphate groups of DNA, they also have a series of nitrogen containing bases that project from the back bone
